METAL ALLOY.

No Drawing.

To all whom it may concern:

Be it known that I, JAMES E. HOLDER, a citizen of the United States,residing at Green Lane, in the county of 'Montgomery and State ofPennsylvania, have invented certain new and useful Improvements in MetalAlloys, of which the following is a specification.

This invention relates to improvements in metal alloys, and the objectis to provide an alloy that will adapt itself to general uses in thereduction or melting down of certain metals, used in the arts fordifierent purposes, and the invention consists in combining certainmetals by means of a specified method, which will be described later,and

in combining said metals in proportions that may differ under certainconditions, and when intended for use in different metalliccombinations.

The invention consists broadly in the method of combining copper andlead, in certain proportions, with any or all of the following, Viz:iron, manganese and phosphorus, in relatively smaller proportions, by

the use of nickel and metallic arsenic.

The approximate proportions of the respective ingredients are asfollowsz Lead, from 30 to per. cent, I Copper, from 47 to 68 per cent.

Nickel, from 1 to 5 per cent. Metallic arsenic, from to 11} per cent.Manganese, 2% per cent. Phosphorus, T} of 1 per cent. T v Iron,-% of lper cent.

The proportions enumerated above are the approximate relativeproportions and their ranges, as they will appear in the resultant.

product.

The method .of carrying out my invention, is as follows First an alloyis made of metallic arsenic and lead andthis is poured into smallingots,

for convenience in handling. Then, copper Specification of LettersPatent. Patent d N6 16 1920 Application filed June 2, 1920. Serial No.386,052.

and nickel are melted, under suitable cover, and, when the copper andnickel are fluid, a certain portion of plain lead is added. Thetemperature of the mass is then brought to a hlgh degree, and then thearsenical lead is added to the mass. The entire mass is then drawn,molds.

then well stirred, and skimmed, and run into suitable The introductionof the iron, manganese and phosphorus is a matter that will bedetermined in each case, any or all of them being added to the mass atdifferent times dur ng the process, and the proportions while subject tovariation are always relatively low, for the reason that these elementsare included principally for the toughening effect, and for the aid theysupply in holding up the lead content.

lVhat I claim is 1. 3A metallic compound containing lead,copper,"nickel, metallic arsenic, manganese, phosphorus and iron inspecified.

the proportions 2. A- compound comprising lead, copper,

mass and then adding the arsenical lead,

stirring the entire mass and then running it into molds.

. In testimony whereof I aflix my signature.
